1.6.3 RPM

The Black/White wire (Pin 18) should be connected to a suitable RPM signal. A

suitable signal would be either 0 –12 Volts or 0 – 5 Volts .

A suitable RPM signal can be found using any of the following techniques.

• Wiring diagrams - If you have a wiring diagram of the vehicle find an RPM signal.

• Tachometer – There is usually an RPM signal leading to the back of the

dashboard. (Highly Recommended)

• Coil signal – note, if the car has twin coils the cylinder value in the traction control

menu may need to be changed. e.g. 6 Cylinder engine, twin coils, set cylinders to

3 if RPM is picked up off one coil.

• Diagnostic Connector – Some cars have a diagnostic connector, these will

normally have a RPM signal. e.g. pin1 on BMW Diagnostic Socket.

•

ECU – most cars will have an RPM signal going into the ECU.

Once a suitable RPM signal has been found, follow the procedure below for

connecting the RPM wire to the RPM input of the traction control.

• Strip back the insulation of the RPM wire exposing the cores.

• Tin the cores using the soldering iron and solder.

•

Strip back the insulation of the traction control wire.

• Tin the cores using the soldering iron and solder.

• Solder the traction control Wire to the RPM wire.

• Cover the joint with insulation tape.

The RPM connection can be tested using either a laptop computer or the diagnostic

facility on the traction control. This is explained in Section 7.2 Diagnostic Modes.
